文家坡矿4105工作面冲击地压防治措施研究

Study on Prevention and Control Measures of Rock Burst in the 4105 Working Face of Wenjiapo Coal Mine

陕西彬长文家坡矿4105工作面强矿震、冲击地压机理复杂、影响因素繁多导致灾害突发性大,通过分析4105工作面布置、地质构造以及煤层顶底板情况,得出了工作面冲击主控因素与诱发机理,并制定针对性的预卸压措施,及时利用冲击地压监测手段对其监测检验治理效果。经现场实践表明,该措施能有效解决来压强度过大问题,使得4105工作面冲击地压危险性显著降低。

Strong mine earthquake,complex rock burst mechanism and various influencing factors lead to sudden disaster in the 4105 working face of Binchang Wenjiapo Coal Mine in Shaanxi Province.Through the analysis of the 4105 working face layout,geological structure and coal seam roof and floor,the main controlling factors and inducing mechanism of working face impact are obtained,and targeted pre-pressure relief measures are formulated to monitor and test the control effect by means of rock burst monitoring in time.The field practice shows that this measure can effectively solve the problem of excessive pressure strength and significantly reduce the risk of rock burst in the 4105 working face.
